NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared gentle is giving astronomers hints on the dynamical processes occurring inside the supernova remnant. Tiny clumps represented in vivid pink and orange make up the supernova’s internal shell, and are comprised of sulfur, oxygen, argon, and neon from the star itself. A big, striated blob on the backside proper nook of the picture, nicknamed Baby Cas A, is likely one of the few gentle echoes seen NIRCam’s subject of view. In this picture, pink, inexperienced, and blue had been assigned to Webb’s NIRCam information at 4.4, 3.56, and 1.62 microns (F444W, F356W, and F162M, respectively).
